Research shows green roofs help bees get around

Recent research in Switzerland shows that green roofs increase the biodiversity of bugs in urban areas, particularly bugs that crawl but don’t fly. But for flying bugs, especially bees, green roofs may be even more important – providing a great way for them to connect to more ecosystems, and more food sources.

This research is the first of its kind to show that green roofs serve as stepping stone corridors for arthropods. One final thought on the paper is that there was no effect on green roof size – small green roofs had the same connectivity effect as large ones. This paper is the first of its kind to show that green roofs can increase urban arthropod biodiversity through connectivity.
